i recently discovered UFOHD2 as a great tool and want to try to analyze an old database of nightskycapture videos i did not capture with UFOHD2.
Is there an easy way to this? I tried some reencoding and even streaming the videos with an virtual camera but nothing worked so far.

Sorry, it was tried, but aborted.
Un-compressed and continuous video stream from 1 minute before the event is essential for UFOCapture.
But there were so many varaiety of videos, most of recorded videos are stored using some compressions or did not have preceding part, so a general tool could not be built.

Thank you for your answer.
The Videos are each 4-10h long, so the required preceding 1min wouldn't be a problem.
Unfortunatly I do not have a camera to test the software and some scenarios myself so i have to ask:

-> Does UFOCaptureHD2 support detection of captured videos afterwards in general?

-> If reencoded, retaged, renamed and placed in UFOCaptureHD2-comform folders correctly does UFOCaptureHD2 accept those videos "as it's own"?
--> If yes what codecsettings, filename- and folderpattern must i use?

-> When i try to "stream" the videos using MagicCamera and VLC UFOCaptureHD2 briefly shows the stream after I click preview or detect but crashes almost immediately under Win7 and WinXP. Windows 7 returns the following errormessage:
